Opis:: In this work, tin oxide ($SnO_2$) films were deposited on multiwall carbon nanotube buckypaper using a rf magnetron sputter process in a mixed oxygen/argon (1/9) gas environment. Conditions for the growth of $SnO_2$ thin films on multiwall carbon nanotube buckypaper by rf sputtering are: target composition $SnO_2$ (99.999 wt%); total system pressure 1 Pa; sputtering power (rf) 75, 100 and 125 W, respectively; $O_2//Ar$ (1/9) gas mixture. The surface morphology of the $SnO_2$ multiwall carbon nanotube composite films was investigated by scanning electron microscopy. The crystallographic structure of the sample was determined by X-ray diffraction. The electrochemical properties of $SnO_2$ multiwall carbon nanotube composite anodes were investigated by galvanostatic charge-discharge experiments.

Opis:: In this work, the effect of rf power on the structural, electrical and electrochemical properties of ZnO thin films was investigated. ZnO thin films were deposited on glass and Cr coated stainless steel substrates by rf magnetron sputtering in pure Ar gas environment. ZnO thin films for different rf powers (75, 100, and 125 W) were deposited keeping all other deposition parameters fixed. ZnO thin films were used as negative electrode materials for lithium-ion batteries, whose charge-discharge properties, cyclic voltammetry and cycle performance were examined. A high initial discharge capacity about 908 mAh g^{-1} was observed at a 0.5 C rate between 0.05 and 2.5 V. The crystallographic structure of the sample was determined by X-ray diffraction. The electrical resistivity of the deposited films was measured by the four-point-probe method. The thickness of the ZnO thin films was measured using a profilometer.
